In this guide
The JEE Main syllabus looks long on paper — around fifty units across three subjects. Read it closely, though, and it becomes manageable. Most units build on a small set of foundations, the official list tells you exactly what is in and out, and the chemistry syllabus follows NCERT more closely than many aspirants assume.
This guide walks through the syllabus as NTA publishes it, notes what was removed for the 2024 exam, and suggests an order that makes each chapter easier than the one before.
Where the syllabus comes from
NTA publishes the syllabus for Paper 1 in the Information Bulletin and on jeemain.nta.nic.in. It is based on the Class 11 and 12 physics, chemistry and mathematics taught through NCERT textbooks, with some topics trimmed.
Before the 2024 exam, NTA reduced the syllabus. Recent sessions have used that reduced list.
Physics: 20 units
| Area | Units in the syllabus |
|---|---|
| Mechanics | Units and measurements; kinematics; laws of motion; work, energy and power; rotational motion; gravitation; properties of solids and liquids |
| Heat | Thermodynamics; kinetic theory of gases |
| Oscillations and waves | Oscillations and waves |
| Electricity and magnetism | Electrostatics; current electricity; magnetic effects of current and magnetism; electromagnetic induction and alternating currents; electromagnetic waves |
| Optics | Ray and wave optics |
| Modern physics | Dual nature of matter and radiation; atoms and nuclei; electronic devices (semiconductors) |
| Practical | Experimental skills |
The communication systems unit was removed in 2024, along with some sub-topics in other units.
Mechanics carries the most units and underpins everything else. Rotational motion and electromagnetism are the chapters where most aspirants lose marks, because both need clear pictures of vectors and directions. Modern physics and semiconductors are short and formula-driven, which makes them good-return chapters.
Chemistry: 20 units in three parts
| Branch | Units |
|---|---|
| Physical | Some basic concepts (mole concept); atomic structure; chemical bonding and molecular structure; chemical thermodynamics; solutions; equilibrium; redox reactions and electrochemistry; chemical kinetics |
| Inorganic | Classification of elements and periodicity; p-block elements; d- and f-block elements; coordination compounds |
| Organic | Purification and characterisation of organic compounds; basic principles of organic chemistry; hydrocarbons; organic compounds containing halogens; containing oxygen; containing nitrogen; biomolecules; principles related to practical chemistry |
Chemistry lost the most in 2024. Units such as states of matter, surface chemistry, environmental chemistry, polymers and chemistry in everyday life no longer appear in the list, along with the s-block and hydrogen chapters and metallurgy.
Each branch needs a different kind of work:
- Physical chemistry is numerical. It rewards formula fluency and clean arithmetic, much like physics.
- Inorganic chemistry is factual. Questions often test a specific line, table or trend from NCERT.
- Organic chemistry is about mechanisms and reaction chains. Understanding general organic chemistry (GOC) first makes the rest far easier to remember.
Mathematics: 14 units
| Area | Units |
|---|---|
| Algebra | Sets, relations and functions; complex numbers and quadratic equations; matrices and determinants; permutations and combinations; binomial theorem; sequences and series |
| Calculus | Limits, continuity and differentiability; integral calculus; differential equations |
| Coordinate geometry | Straight lines, circles and conic sections |
| Vectors and 3D | Vector algebra; three-dimensional geometry |
| Others | Statistics and probability; trigonometry |
Mathematical induction and mathematical reasoning were removed in 2024, with some sub-topics trimmed elsewhere.
Calculus, algebra and coordinate geometry together make up most of the paper in a typical session. Vectors and 3D geometry are compact and often scoring. Trigonometry rarely appears as many stand-alone questions, but it is inside almost every calculus and coordinate problem.
Where the questions tend to cluster
Exact chapter counts change from shift to shift, and no one can promise how many questions a chapter will get. Broad patterns are more stable:
| Subject | Consistently heavy areas | Short, good-return areas |
|---|---|---|
| Physics | Mechanics; electricity and magnetism | Modern physics; semiconductors; units and errors |
| Chemistry | Physical chemistry numericals; organic reactions | Coordination compounds; biomolecules; periodicity |
| Maths | Calculus; algebra; coordinate geometry | Vectors and 3D; statistics; matrices |
Class 11 and Class 12
Class 11 and Class 12 both contribute substantially. Class 11 contains most of mechanics, the foundations of physical chemistry, GOC, and algebra and coordinate geometry. Class 12 adds electromagnetism, modern physics, much of organic chemistry and calculus.
The trap is timing. In Class 12, school and boards pull attention towards Class 12 chapters, and Class 11 quietly fades. Candidates then find their weakest marks in Class 11 chapters they "already finished". A fixed weekly Class 11 revision slot, kept all through Class 12, prevents this.
What NCERT covers and what it doesn't
| Part | Is NCERT enough? |
|---|---|
| Inorganic chemistry | Most questions are built on NCERT text, tables and exceptions. Read it line by line, more than once. |
| Organic chemistry | NCERT reactions and named reactions are the core; add mechanism practice. |
| Physical chemistry | NCERT theory is the base; you need many more numericals. |
| Physics | NCERT for concepts; JEE needs far more problem practice. |
| Mathematics | NCERT builds basics; JEE-level problems need a dedicated question source. |
A study order that builds on itself
- Physics: units and measurements, kinematics and laws of motion first. Then work-energy, rotation, gravitation. Electrostatics before current, current before magnetism, magnetism before EMI.
- Chemistry: mole concept first — it appears inside every physical chemistry chapter. Atomic structure and bonding next. Start organic with GOC and isomerism before reactions.
- Maths: functions, quadratic equations and trigonometry early. Then limits, differentiation and integration in sequence. Coordinate geometry after straight lines are solid.
- Inorganic chemistry: in small doses throughout the year, revised repeatedly, rather than crammed at the end.
The subject plans go deeper: physics plan, chemistry plan and maths plan.
Common mistakes
- Studying deleted topics. Old books and reference papers still contain them. Check each chapter against the current list before investing time.
- Ignoring experimental skills and practical chemistry. These are listed units and can carry questions.
- Treating inorganic as "last month" work. It is memory-heavy and needs spaced revision.
- Chasing chapter-weightage charts. They describe past papers, not your paper.
What to do next
- Print the official syllabus and tick each unit as done, revised once and revised twice.
- Mark your three weakest units in each subject.
- Fix a weekly Class 11 revision slot.
- Check every reference book chapter against the current list before starting it.
